Abstract: A lighting device includes a linear light source extending in a first direction and configured to emit light in a second direction intersecting the first direction to an object; a rod lens apart from the linear light source in the second direction and extending in the first direction, the rod lens configured to transmit the light emitted from the linear light source; and a support portion supporting the rod lens and having: a first surface extending in a third direction intersecting the second direction; and a second surface extending in a fourth direction intersecting the second direction and the third direction. The rod lens is in contact with each of the first surface and the second surface.

Abstract: An image forming apparatus that has a monochrome mode and a full color mode as image forming modes, includes: a power supply unit configured to supply power thereto; a main power switch configured to turn on and off the power supply unit; a mode switching unit configured to selectively and manually be switched between the monochrome mode and the full color mode, wherein the main power switch and the mode switching unit are integrally formed as one mode switch; a power supply interrupting unit configured to interrupt power supply to a part that is necessary to form an image in a mode other than the monochrome mode, when the mode switch is set to the monochrome mode.

Abstract: A cleaning device, a process cartridge, an image forming apparatus, and toner to maintain improved cleaning performance for a long time. The cleaning device includes a cleaning blade, a lubricant applying part, and a toner removing part. The cleaning blade is disposed in contact with a surface of an image bearing member. The lubricant applying part coats a solid lubricant on the surface of the image bearing member, and is disposed in an upstream side from the cleaning blade with respect to a rotational direction of the image bearing member. The toner removing part removes toner particles, and is disposed in an upstream side from the lubricant applying part with respect to the rotational direction of the image bearing member.

Abstract: A knife having a blade made of stainless steel and a hollow handle made of stainless steel. The hollow handle has right and left handle halves which are butt-joined to each other at their joining faces. The handle halves define therebetween a hollow portion which is filled with a filler, which may be river sand, for adjustment of the overall weight balance of the knife. The blade and the handle are butt-joined into one piece at their confronting end edges.

Abstract: An automatic cut-sheet feeding apparatus includes a feed roller which rotates in a direction so as to feed in and feed out an upper most cut-sheet, and means for stopping the feeding of excessive cut-sheets which should not be fed out together with the uppermost cut-sheet when a plurality of cut-sheets are fed in together by the feed roller, and thereby automatically feeding cut only the uppermost cut-sheet of the stack of cut-sheet one by one, the stopping means includes a holder pressed against said feed roller, a push-piece supported on the holder and pressed at a position preceding a position where the holder makes contact with said feed roller along a direction in which the cut-sheet is transported thus causing excessive cut-sheets to curve downwards when a plurality of cut-sheets pass between the feed roller and the push-piece, and a stop surface disposed to confront a leading edge of the curved excessive cut-sheet and engage the leading edge thereof.
